Topic: pointers, dynamic array and command line arguments Write a complete C++ program named “showHelp” that accepts command line arguments.  It checks whether there is a command line argument of “/help” or “/?” or “-help” followed by a topic number.  It will print out “yes, topic number() if there is one.  Otherwise, it prints out “no, topic number(N/A)  For example, if you run this program with correct arguments as follows, it will print out yes and its associated topic number respectively showHelp /? 101 showHelp /debug /help 102 showHelp /print /help 103 /verbose showHelp -verbose -debug -help And if you run the program with invalid arguments, it will print no, in all cases showHelp -help showHelp 101 /? showHelp 101 102 /help /verbose showHelp /? /help -help Note: command line arguments are simply an array of pointers to C-string.   example code: #include using namespace std;   int main(int argc, char** argv){...}

In C++ struct myGrades { string class; char grade; };   Declare  myGrades as an array that can hold 5 sets of data and then set a class string in each position as follows: “Math” “Computers” “Science” “English” “History” and give each class a letter grade

C++ Coding Help (Operators: new delete) Assign pointer myGas with a new Gas object. Call myGas's Read() to read the object's fields. Then, call myGas's Print() to output the values of the fields. Finally, delete myGas. Ex: If the input is 14 45, then the output is: Gas's volume: 14 Gas's temperature: 45 Gas with volume 14 and temperature 45 is deallocated.   #include <iostream>using namespace std; class Gas {   public:      Gas();      void Read();      void Print();      ~Gas();   private:      int volume;      int temperature;};Gas::Gas() {   volume = 0;   temperature = 0;}void Gas::Read() {   cin >> volume;   cin >> temperature;}  void Gas::Print() {   cout << "Gas's volume: " << volume << endl;   cout << "Gas's temperature: " << temperature << endl;}  Gas::~Gas() { // Covered in section on Destructors.   cout << "Gas with volume " << volume << " and temperature " << temperature << " is deallocated."…

In C++, When an array is passed to a function as a pointer, the function doesn't know the size of the array. List 3 ways to handle this problem.

In C programming: Write a function printAllCourses() which receives an array of course pointers and the array’s size, then prints all courses in the array by calling printCourseRow()

In C++ Create a function named printArray (). The function has two parameters . The first parameter is an array called finalGrades [ containing integer elements . The second argument is an integer named size OfArray , the number of elements in the array. The function prints the contents of arrayit does not return a value. Write the function header and the function body to print the contents of the array.

use c++ Programming language  Write a program that creates a two dimensional array initialized with test data.  Use any data type you wish .  The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal:  This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two…

In c++, please and thank you! Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.

In C, in order to do operations to the data being referenced by a pointer you would need to use the (*) operator, which is called ______________ operator.

What do you need to know to dereference a pointer?
